Perfluorobutanesulfonyl Fluoride PFBSF CAS 375-72-4, for Fluorinated Fine Chemicals, Surfactants, and Functional Material Synthesis Applications

1. Product Overview

Perfluorobutanesulfonyl Fluoride (abbreviated as PFBSF) is an important perfluoroalkylsulfonyl fluoride fluorinated fine chemical.

This product features a perfluorobutyl chain structure and a reactive sulfonyl fluoride (SO₂F) functional group, combining the excellent heat resistance and chemical corrosion resistance of perfluorinated compounds with the strong reactivity of the sulfonyl fluoride group. It serves as a key intermediate for the synthesis of perfluorosulfonates, fluorinated surfactants, and functional fluorinated materials.
